Top 10 inventions in 20th century
There can be no doubt that the twentieth century is one of the most remarkable in human history for its previously unparalleled rate of technological advances and scientific discoveries, a rate that continues to this day.
In fact, there were so many new gadgets inventions and discoveries made in the last century that it’s difficult to pare the list down to just the ten (which is why there will be a number of glaring omissions from my list). However, I think I have managed to whittle it down to those ten innovations or technologies that have had the greatest influence on humanity—both positively and the negatively. And so, without further ado and in no particular order, here are my nominees for the ten greatest inventions/discoveries of the twentieth century:
Not only did it suddenly make it possible for a person to be heard from hundreds or even thousands of miles away without the use of a wire. Today, it seems to only be useful in the car as a means of keeping the driver from falling asleep behind the wheel or as a tool of talk radio designed to disturb the masses. In its day, however, it was every bit as vital to expectations as the television, the computer, the microwave, and the cell phone are to us today.
Antibiotics playing an important role to save the people from the disease. After Alexander Fleming discovered penicillin in 1928, it reduces the death due to bacterial infection and making longer life-span. It also curing from small pox and typhoid. Antibiotics are treats easily.
Without this the entire world struck. It help us to learn, to update the day today news, makes awareness to people, entertainer and story teller. Yes, I know it destroys brain cells and renders people emotionally and psychologically damaged, but really, where would we be without the boob tube? It makes unity in the family whenever eat we all sitting together and having food. Worse, most of us would have no idea what to do with our time without it, which is probably the saddest commentary of all.
From 20th century we started flying, shrinking our planet to the point that a person could fly anywhere in the world in a matter of hours. Not only have they made travel quick and safe, but aircraft provide many other services as well: from crop dusting and fighting forest fires to overnight delivery of packages and chasing hurricanes. This saves our time from travelling more time.
Until 20th century it dint became most practical and reliable source of transportation ever invented and people the world over still cannot imagine life without them. Most of all, Henry Ford’s assembly-line production style made the automobile affordable and accessible to the average person.it also brought traffic in the market place. The automobile gave everyone a personal freedom our forefathers could only dream of, but we are living with that and turned entire generations of teenagers into raging redheads.
The Personal Computer
Without computers world is none!
Today, of course, they are everywhere and we have become so dependent upon them that many people almost feel naked without one. Someone living because of them nowadays. We use them to keep track of our finances, write books, design logos and sell real estate. Our economy goes down if it goes off from us. Plus, for entertain us with music, movies, and games. Thinking of ancestor without computer those days at this times.
It came before three thousand years ago as the Chinese war weapon and destroyed lives in 20th century. Most importantly, now they became controllable, which suddenly made them useful both as weapons of war and purposely using for some facts. Without the rocket, it is safe to say we cannot visited every planet in our solar system. Rockets also place satellites into orbit around our planet, so without them no GPS, predict the weather, make international calls or, for the most part, even use our cell phones much of the time.
The first true submarine was invented in the 1880’s, it wasn’t until the twentieth century that the modern submarine came into its own. Today the submarine nearly unlimited range in capacity. The two types of ship: submarines and targets. How useful and effective is the modern submarine?
Suddenly humanity had a power source that didn’t pollute, was efficient and practically unlimited, and so had the potential to change the planet overnight. Unfortunately, it was a two-edged sword in that this same energy source could be used to create the most destructive weapons in history, threatening human survival with its very presence. While the third world war and, when operated safely, nuclear power plants truly are a superb and cost-efficient energy source that has the capacity to power entire cities.
The duplicate print of the original which reduces the hand work and made the world simple by printing and making photocopy. Started the service by grayscale prints then later it had a capability to develop colour images and prints. Having many types of printers and its effects. Xerography may finally supplant traditional printing for the production of books and magazines.
